ebinmaine 68,336 #3 Posted April 6, 2021 From another trucker... Engine oil should be straight 30. Brand is as personal as anything. I use Kinetix and order it online by the case. Price is good. It has the appropriate amounts of zinc phosphate in it for older engines. I can send a link if your interested. Transmission filter should be Wix 51410 or Napa 1410. Fram is not preferred. Transmission fluid in a '73 is likely engine oil. Perhaps @953 nut or @pfrederi could help there. 1 Share this post Link to post Share on other sites
rjg854 11,475 #4 Posted April 6, 2021 (edited) easy to check which transmission oil you have, if it's red it's automatic transmission oil if it's tan it's regular oil don't switch from one to the other, always use what you drain out Edited April 6, 2021 by rjg854 add 1 Share this post Link to post Share on other sites
The Tuul Crib 7,337 #5 Posted April 6, 2021 (edited) T😎 Good lookin tractor! The motor oil l use is rotella 30w w T1 .The trans filter wix 1410 you can get at NAPA. Check the color of your trans fluid if it's Amber use 10W30 if it's pinkish color use ATF. Dex Merc you can also get at NAPA.Dont mix what is in the trans.

WHX?? 49,157 #7 Posted April 6, 2021 Cat Yes 10w30. Some guys prefer synthetic for best cold weather performance. Some guys also stick with the OEM filters Part# 79-5270 or 5990 I just use the NAPA in all of mine. 1 Share this post Link to post Share on other sites

WHX?? 49,157 #11 Posted April 6, 2021 Might want to check some other things we always do on a new to us. Air filter, fuel lines & filter, electrical connections, lube cables etc. Check the manual Ed has posted for other maintenance. We also have repair manuals for the transmission and engine if needed. 1 Share this post Link to post Share on other sites

cat man 137 #23 Posted April 6, 2021 do you no how much oil i need for each one motor and rear end? Share this post Link to post Share on other sites
ebinmaine 68,336 #24 Posted April 6, 2021 7 minutes ago, cat man said: do you no how much oil i need for each one motor and rear end? Engine is 1.5 or 2 quarts I think. Transmission I'm not sure but I want to say about five quarts. May want to confirm with others but I don't think the transmission needs to be anything special for oil usage 1 Share this post Link to post Share on other sites
The Tuul Crib 7,337 #25 Posted April 6, 2021 The sunstrand holds at least five yes. I may have put a half quart more after filter 1 1 Share this post Link to post Share on other sites
